[jsr-314-open-mirror] [jsr-314-open] Attribute and State Management in Custom ClientBehaviors

Hi, When working on a custom client behavior implementation, I've noticed that there is no state helper that we have for UIComponent. Also checked implementation of AjaxBehavior in mojarra&myfaces and there seems to be a lot of private implementation of state management, evals, handling of valueexpressions. So my question is do I miss something because it doesn't seem to be trivial process to create a clientbehavior properly with attributes and handle state management. Thanks, Cagatay
